I MACHINE FOR SETTING LACING-HOOKS.

SPECIFICATION forming part of Letters Patent No. 526,295, datedSeptember 18, I894.

' Application filed March 21,1894. Serial No. 504,486. (No model.)

To all whom it may concern} I Be it known that I, ISAAC E. CHANDLER, of

Providence, in the countyof Providence and State of Rhode Island, haveinvented certain new .and useful Improvements in Machines for SettingLacing-Hooks; and I hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawings, forming part of this specification.

This invention relates to machines for attaching lacing studs to bootsand shoes or other articles, and it has for its object to provide asimple, durable, and effective means for feeding such studs to positionfor attachment, rigidly supporting and holding the studs while they arebeing attached, and positively moving each stud with the article towhich it has been attached, forward from the point of attachment, beforethe next stud reaches said point, so that the studs will be properlyspaced and each stud prevented from being injuredby the setting devices.

To this end, the invention consists in the improvements which I will nowproceed to describe and claim.

Of the accompanying drawings, forming a part of thisspecification,-Fignre 1 represents a side elevation of a machineembodying my invention, the stud reservoir being omitted. Fig. 2represents an end view of the same. Fig. 3 represents a bottom plan Viewof the roadway, the yielding detent that secures the engagement of thestuds with the spacing wheel, and the yielding plate or presser whichforces the necks of the studs against the anvil portion of the roadway,the spacing-wheel being omitted, and a part of the supporting frameshown in section. Fig. 4 represents a perspective view of the studspacing-wheel detached. 1

The same figures of reference indicate the same parts in all the views.

In the drawings-5 represents the supporting frame, which may be ofany'suitable form, and as here shown has a recess 6 toreceive a portionof the work or article to which the lacing studs are to be attached, anda head 7 above said recess. The lacing studs to be set move down aroadway 27 from a reservoir (not shown) said reservoir being preferablyanvil portion of provided with automatic means for delivering the studstothe roadway in such position thatthe hook portions of the studs willbestride one edge of the roadway, the heads of the studs being at oneside, andthe shanks .(here shown as eyelet-shaped) at the oppositesideof the roadway. The roadway is a -metal plate attached to a suitablesupport, as

by arms 26 26 affixed to the head 7, and exthe studs will slidedownwardly on the roadway by gravitation to the spacing-wheelhereinafter described, suitable meansbeingemployed to prevent thehooksfrom leaving the roadway during their downward movement. In the presentcase, the roadway is located in such proximity to the vertical face ofthe head 7 that said face constitutes a guard to keep the studs in placeon the roadway during their downward movement, there being anarrow spacebetween said face and the inner edge of the roadway of sufficient widthto accommodate the necks which connect the heads with the shanks of thestuds, as shown in Fig. 1. i

The supporting frame is provided with a tends downwardly from thereservoir, so that horizontal bearing in which isjournaled a shaft 10,to one end of which is affixed the stud-feeding and spacing-wheel 21.Said wheel has pockets in its periphery, as shown in Fig. at formed toengage the heads of the studs which pass down the roadway, the wheelbeing rotated step by step as hereinafter described, and located so thateach partial rotation will bring one of the pockets into engagement withthe head of one of the lacing studs on the roadway, and cause a positivemovement of said stud onto or toward the the roadway hereinafterdescribed. y I

I The head 7 is provided with ayielding detent 15, adapted to arrest thecolumn of studs on the vertical portion of the roadway and hold thelowest stud of the column in such. position that it will be engaged bythe next advancing pocket, said detent being here shown as a bolt orstud having a convex outer end and fitted to slide in a socket in thehead 7, a spring 14 being employed to project said detent into the pathin which the necks of the hooks move from the roadway.

The rear end 23 of each pocket is preferably substantially at a rightangle with the bottom of the pocket, so as to form a square shoulderadapted to positively engage and force forward a lacing stud, while theforward end 24 of each pocket is preferably beveled, as shown in Figs. 2and 4. A part of the roadway is curved to conform to a portion of theperiphery of the spacing-wheel, as shown in Fig. 1, and the curvedportion terminates in a substantially horizontal extension of theroadway located below the spacing- -wheel. Said horizontal portion Iterm the anvil, because it co-operates with thesettingdie hereinafterdescribed, in setting or clinching the shanks of the studs against theunder side of the work. The studs are moved onto the said anvil by thespacing-wheel, and their necks are at the same time pressed against theinner edge of the anvil, to insure the correct position of the shanksupon the anvil, by means of a presser 13, which is a plate fitted toslide in a dovetail guide in the head 7 and pressed outwardly by aspring 13', said plate being arranged to bear against the necks of thestuds that are moved by the spacingwheel onto the anvil.

18 represents the setting-die, which co-opcrates with the anvil abovementioned, in clinching or setting the shanks of the lacing hooks. Saiddie is fitted to move vertically in a socket in the projecting portion 8of the supporting frame, and islocated below the anvil. Means areemployed for vertically reciprocatin g the setting-die, said means ashere shown being'a lever 16 pivoted at 16 to the supporting frame andprovided at one end with an arm 17 which enters a slot 9 in theprojection 8 and supports the setting-die 18. Said lever is oscillatedby any suitable mechanism, and is provided with a pawl 19 which engagesa ratchet 2O aflixed to the spacingwheel shaft 10, the arrangement beingsuch that when the lever is moved in one direction it raises thesetting-die without rotating the spacing-wheel; and when moved in theopposite direction, it depresses the setting-die and at the same timeimparts a partial rotation to the spacing-wheel.

The operation-is as followsz-At each partial rotation of thespacing-wheel, a pocket therein engages the lowest stud of the columnsupported by the detent 15, and separates said stud from the column andmoves it along the curved portion of the roadway. The extent of eachmovement of the spacing-wheel may be such as to bring the engaged studat once to position over the setting-die; but as here shown, twomovements of the wheel are required. When the wheel stops, thesettingdie rises and upsets the shank of the stud held over it by thewheel upon the anvil, thus attaching the stud to the work, the latterhaving been previously inserted between the setting-die and the anvil.The setting-die then descends, and the spacing-wheel is given anotherpartial rotation, which causes it to an extension of the roadway isnecessarily somewhat slender, is supported by the spacing-wheel againstthe upward pressure exerted by the setting-die, and is thus preventedfrom yielding to said pressure. I prefer to attach a disk or collar 25to the shaft of the spacing-wheel at the outer side of the latter,

the periphery of said collar being flush with that of the spacing-wheelbetween the pockets, the collar affording additional bearing and supportfor the anvil. I also prefer to provide the head 7 with a rigidprojection or hearing 11 located over the spacing-wheel, with its underside in close proximity to the periphery of said wheel, said projectionbeing adapted to support the spacing-wheel against upward pressure fromthe setting-die.

\ It will be seen that by forming the roadway to serve both as a roadwayand an an- 1 vil, and arranging the spacingwheel so that it not onlyproperly locates the studs upon the anvil but also removes themtherefrom and supports the anvil against the pressure of thesetting-die, I materially simplify the construction of the machine.

I claim- 1. The combination of a chute or roadway having its lowerportion formed to serve as an anvil; a stud-spacing wheel located at oneside of the anvil and provided with pockets to engage the heads of thestuds of the road way; means for rotating said wheel step by step,whereby it is caused to first advance a stud to the anvil, then hold itrigidly upon said anvil in position to be set, and finally remove itfrom said position; and a reciprocating setting-die or plunger whichco-operates with the anvil in setting the shank of a lacing studthereon, the anvil being supported by the spacing-wheel against thepressure of the setting-die.

2. The combination of a chute or roadway having its lower portion formedto serve asrigid bearing on the frame of the machine arranged to supportthe spacing-wheel and anvil against the pressure of the setting-die.

3. The combination of a chute or roadway having its lower portion formedto serve as an anvil, a stud-spacing wheel located at one side of saidanvil and provided with pockets to engage the heads of studs on theroadway, means for'rotating said wheel step by step, a yielding detentarranged to arrest the studs on the roadway and cause their engagementwith the pocketsof the spacingwheel, and a reciprocating setting-die orplunger which co-operates with the anvil in setting the shank of alacing stud thereon.

4. The combination of a chute or roadway hand. having its lower portionformed to serve as an anvil; a stud-spacing wheel located at one side ofsaid anvil and provided with pockets to engage the heads of studs on theroad- ISAAC E. CHANDLER.
